FAUCET.

SPECIFICATION forming part Of Letters Patent No. 668,355, dated February19, 1901.

Application filed May '7, 1900. Serial No. 15,667. No model.)

To aZZ whom it may concern:

Be it known that I, ISAAC OSGOOD, a citizen of the United States,residing at Amesbnry, in the county of Essex, State ofMassachusetts,have invented a certain new and useful Improvement inFaucets, of which the following is a specification, reference being badtherein to the accompanying drawings.

At times it becomes necessary to close the connection between astreet-main and the water-pipes of a house system. A cock is providedfor the purpose, as is well known, the same being located usually in thecollar of the house. In connection with the said cock is provided awaste or drainage orifice, which is opened by the operation of closingthe cock. Through this orifice water contained in the higher portions ofthe piping escapes, it being intended that thereby the said upperportions shall become emptied of their contents in order to preventdamage from freezing in cold weather and sometimes for other reasons. Asis well known, ordinarily it is necessary, in order that the water mayall flow down and out at the orifice in question, to open faucets in theupper part of the house, so that air may enter, and thus facilitate theescape of the water.

The aim of the invention is to provide in novel and improved manner forobviating the necessity for opening the faucets by hand to facilitatethe downflow of water and its escape through the discharge or wasteorifice.

The invention consists in a vented faucet embodying certain novelfeatures of construction, which I will now proceed to describe withreference to the accompanying drawings, in which latter I haveillustrated the best embodiments of the invention thatI have yetcontrived.

In the drawings, Figure 1 shows in vertical longitudinal section afaucet containing one embodiment of the invention. Fig. 2 shows,detached, the screw which in Fig. 1 holds the packing and check-valve inplace. a view similar to Fig. 1,showing a modification. Fig. eshows,detached, the valve of Fig. 3. Fig. 5 is a sectional view illustrating athird embodiment. Fig. Gshows views of the valve of Fig. 5.

Having reference to the drawings, 1 desig- Fig. 3 is.

nates the body of the faucet. 2 is the waterpassage therethrough.

3 is the diaphragm.

dis the externally-threaded valve-plug with its handle 5, by means ofwhich to turn the same, and 6 is the packing on the end of the saidvalve-plug working against the usual seat at 7 on the upper side of thediaphragm 3 around the orifice through the said diaphragm.

8 is a screw serving to hold the packing 6 against the end of thevalve-plug 4. The stem of the said screw passes through a central holein the disk 6 of packing and enters a bore 9, extending upwardly intothe end of the valve-plug 4, the said bore being threaded and engaged bythe corresponding thread of the stem of the screwin obvious manner. Inaccordance with the invention I extend the bore 9 inwardly lengthwise ofthe valve-plug 4 farther than is required for the reception of the stemof the screw 8, and thereby form a chamber to receive a check-valve 10.The said check-valve is retained in thesaid chamber by the screw 8. Incontinuation of the bore 9 I form a second and smaller bore 11, which isconcentric with the bore 9. I also form an oblique bore or passage 12through the valve-plug, it intersecting the smaller bore 11 and alsocommunicating directly with the interior space 2 of the body of thefaucet beyond the valve-seat 7 of the diaphragm 3. I form the screw 8hollow or tubular, the central passage therethrough being designated 13.

As will be obvious, the operations of producing the bores 9 and 11 andthe passage 12 in the valve-plug 4 may be quickly and cheaply performed,while the work of assembling requires simply that the valve 10 shall bedropped into the larger bore 9 and that the screw 8 shall be passedthrough the packing 6 and turned into the said bore 9.

When the faucet is applied to the servicepipe of a house and the latteris filled with water under the usual pressure, the said pressure will betransmitted to the valve 10 in consequence of a portion of the waterfinding its way through the passage 13 of the screw 8, and said pressurewill act to raise the said valve against the valve-seat at the inner endof the bore 9. So long as the water continues under pressure within thepipe the valve will be held in close contact with the valve-seat. When,however, the pressure is shut off at the service-cock and thedrainage-orifice is opened, the valve 10 will be forced away from .itsvalve-seat by atmospheric pressure and air will flow inwardly throughthe passage 12 and bore 11, through the larger bore 10, around the valve9, and thence through the passage 13 of screw 8 into the water-space ofthe faucet.

Suitable provision will be made for facilitating the passage of the airby the valve 10 and into the passage 13 of screw 8. Fig. 2 shows theinner end of the screw 8 formed with transverse slots or notches 14 forthe purpose.

The ball shown in Fig. 1 is advantageous for use as a valve, since itcannot become deranged in working through change-of the position thereofand cannot become clogged or cramped in its action.

Figs. 3 and 4 show a cup-shaped valve 100, the convex surface of whichis arranged to make contact with the valve-seat at the inner end of thebore 9, the hollow side of the said valve being turned toward the screw8. The said cup-shaped valve has sufficient length to prevent it frombecoming tilted and cramped in the bore 9, which would interfere withthe proper working thereof.

For the purpose of setting and guiding the cup-shaped valve 100 somewhatthe inner end of the screw 8 is represented in Fig. 3 as reduced indiameter and projecting a short distance into the hollow interior of thesaid cupshaped valve. For the purpose of facilitating the passage of theair by the valve 100 into the central passage of the screw 8 the loweredge of the cup is shown formed with notches 101.

I contemplate in some cases the employiently, as well as at exceedinglysmall cost,

to the common form of faucet at present in extensive use, and thisconsideration has carefully been kept in mind in 'contriving the same.

I claim as my invention- 1. The faucet having the valve-plug thereofformed with the longitudinal bores 9 and 11 and with the passage 12intersecting the said bore 11 and communicating directly with theinterior discharge-space of the faucet beyond the valve-seat within thelatter, the valve occupying the inner portion of the bore 9, the hollowscrew 8 fitting within the said bore and retaining the valve therein,and the packing held to the end of the valve-plug by the said screw,substantially as described.

2. The faucet having the 'alve-plug thereof formed with the longitudinalbores 9 and 11, and means of direct communication between said bore 11and the interior space of the faucet beyond the valve-seat within thelatter, the yielding valve occupying the inner portion of the bore 9,the hollow screw 8 fitting within the said bore and retaining the valvetherein, and the packing held to the end of the valve-plug by the saidscrew, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.I

ISAAC OSGOOD.
